A wrapper script has been created to run X11 applications, called "idev" (interactive-development), or nicknamed "xrun".  This has been installed into /usr/local/bin on login and compute nodes. 

To use it, do the following steps:1)

1. Install an X11 server on your desktop or laptop, e.g. "Xming" on Windows, or "XQuartz" on MacOS. 

...

1. SSH to one of the Talapas login nodes (talapas-login.uoregon.edu) with X11 forwarding enabled:

   ...

   1. 1. If using MacOS or Linux, connect using

   1. 1. ssh -Y

   ...

   ...

   1. Once on a Talapas login node, you have two options available

   ...

   1. , xrun or srun.
      1. Using xrun, you can pass many of the same arguments to xrun as you can to srun.
      2. Using srun,

   ...

   1. 1. use the --x11 flag (available in the Slurm 17.11 module)

   
   

   Code Block
   language text
   xrun -N1 -n1 --time=02:00:00

   ...

      2. use "srun" with the "--x11" option (available in the Slurm 17.11 module), e.g.:

   ...

   
   

   Code Block
   language text
   srun -A hcprcf -N1 -n1 --time=02:00:00 --x11 --pty bash -i

   
   

   4) Launch your X11 application (, e.g. type "xclock")
